Authors' conclusion

Glucose control using the CamAPS FX algorithm with SMA was non-inferior to its use with CC in youth and young adults with type 1 diabetes.

Study context

Population
Youth and young adults (aged 12–20 years) with T1D using MDI, sensor-augmented pump or HCL before enrolment; two University Hospitals in Switzerland43 completed · sensor-augmented pump 4 · or HCL 7

Comparison
Simplified meal announcement (SMA) vs carbohydrate counting (CC) with mylife CamAPS FX HCL
Primary endpoint
Proportion of time glucose in target range (3.9-10.0 mmol/l); non-inferiority margin 5 percentage points
